Vinyl records, reel to real, 8 track cassettes, mini cassettes (like your TDK), CD's, and now all the music you can carry in a tiny USB drive or iPod like device. And look how video and photography has transformed. I had a black and white TV growing up with about 10 channels on a rotary dial. And computers! My first computer had two 5.5 inch floppy drives and no hard drive at all. A ten megabyte hard drive cost about $7,000 at that time, way out of my budget. A big 8 megabytes of RAM and a screen presented in green dots on a black background.

Of course I'm an old fart. You are about my middle daughter's age. Thanks for your reply.
